Iran unveils what it calls a hypersonic missile able to beat air defences amid tensions with US

Iran claimed on Tuesday that it had created a hypersonic missile capable of travelling at 15 times the speed of sound, adding a new weapon to its arsenal as tensions remain high with the US over Tehrans nuclear programme.The new missile -- called Fattah, or Conqueror in Farsi -- was unveiled even as Iran said it would reopen its diplomatic posts on Tuesday in Saudi Arabia after reaching a dtente with Riyadh following years of conflict.

Iran claimed on Tuesday that it had created a hypersonic missile capable of travelling at 15 times the speed of sound, adding a new weapon to its arsenal as tensions remain high with the US over Tehran's nuclear programme.

The new missile -- called Fattah, or ''Conqueror'' in Farsi -- was unveiled even as Iran said it would reopen its diplomatic posts on Tuesday in Saudi Arabia after reaching a détente with Riyadh following years of conflict. The tightly choreographed segment on Iranian state television apparently sought to show that Tehran's hard-line government can still deploy arms against its enemies across much of the Middle East. ''Today we feel that the deterrent power has been formed,'' Iranian President Ebrahim Raisi said at the event. ''This power is an anchor of lasting security and peace for the regional countries.'' Gen Amir Ali Hajizadeh, the head of the paramilitary Revolutionary Guard's aerospace programme, unveiled what appeared to be a model of the missile. Hajizadeh claimed the missile had a range of up to 1,400 kilometres (870 miles). That's about mid-range for Iran's expansive ballistic missile arsenal, which the Guard has built up over the years as Western sanctions largely prevent it from accessing advanced weaponry.

''There exists no system that can rival or counter this missile,'' Hajizadeh claimed. That claim, however, depends on how manoeuvrable the missile is. Ballistic missiles fly on a trajectory in which anti-missile systems like the Patriot can anticipate their path and intercept them. Tuesday's event showed what appeared to be a moveable nozzle for the Fattah, which could allow it to change trajectories in flight. The more irregular the missile's flight path, the more difficult it becomes to intercept. Iranian officials did not release footage of a Fattah successfully launching and then striking a target. Hajizadeh later said that there had been a ground test of the missile's engine. A ground test involves a rocket motor being put on a stand and fired to check its abilities while launching a missile with that rocket motor is much more complex.

Hypersonic weapons, which fly at speeds in excess of Mach 5, or five times the speed of sound, could pose crucial challenges to missile defence systems because of their speed and manoeuvrability. Iran described the Fattah as being able to reach Mach 15 -- which is 15 times the speed of sound. China is believed to be pursuing the weapons, as is America. Russia claims to already be fielding the weapons and has said it used them on the battlefield in Ukraine. However, speed and manoeuvrability isn't a guarantee the missile will successfully strike a target. Ukraine's air force in May said it shot down a Russian hypersonic Kinzhal missile with a Patriot battery. Gulf Arab countries allied with the US widely use the Patriot missile system in the region. Israel, Iran's main rival in the Mideast, also has its own robust air defences. In November, Hajizadeh initially claimed that Iran had created a hypersonic missile, without offering evidence to support it. That claim came during the nationwide protests that followed the September death of 22-year-old Mahsa Amini after her arrest by the country's morality police. Tuesday's announcement came as US Secretary of State Antony Blinken is to begin a visit to Saudi Arabia.
